' Ascending on skis in hilly or mountainous places is extremely hard.The ski is apt to slip back, so that the skier'will soon get tired.

It also frequently happens that a novice.

5 at skiing, when descending,

downhill across a forest, or on stony ground, will lose the command ofhis skis, and rush into obstacles, whereby serious accidents may occur.i

overcome these drawbacks, by increasing the friction of skis.Arrangements in. which strips of sealskin or the like'are fastened-tothe bottom faces of the wooden runners are known. Such skins, howeverare expensive, and liable to wear away when getting wet and,subsequently, freezing in. Moreover, these sealskin strips are eitherpasted on or otherwise securedto the skis by some compli cated device bywhich. an eventually present anti-friction wax layer will be injured.

The device according to the invention comprises a very great number ofmetal teeth fastened to the bottom of the skis. These metal teeth orbarbs are similar to the cards used in textile works, and, like them,are best stuck through a strip of leather or the like, which is fastenedto the ski by means of straps, or lace. facture of these teeth orbarbs'has, preferably, a triangular cross section, and theteeth arefastened to the skis in a manner'which,

" when the skier'is progressing, will permit one one edge of thetriangle to cut the snow, while the opposite side willopposeconsiderable resistance to slipping downhill.

In the drawing, vention is shown by way of example. Figure 1 is a viewof the non-slipdevice seen from below, Figure 2' is a section on theline I-.I of Fig. 1. Figure 3 shows a cross section of the wire used forthe manufacture of said teeth, on anenlargedscale, the; direction'of thecourse being indicated by an arrow. Numerous wlre teeth 2 are run, inrows, through a strip of'leather or the like 1. The simplest way toeffect this is similar to the manner in which this is accomplished incards, namely,"

to bend bits of wire to U-form and stick said wires throughthe strip 1.The ends of the or traveling The object of the present invention is to'The wire used for the manubits of wire are bevelled, and the teeth arerun in such a manner that the angle contained between them and thedirectionof the course indicated by the arrow A is an obtuse angle on.To protect said leather strip from wear, a 1 metal sheet maybe appliedto the bottom face of said strip, from which sheet the teeth will.

project.

The fastening of the strip 1 to a ski may be effected by pasting to theback of thestrip a support 3 of waterproof fabric, to which supportstraps 4 and 5 are attached. To the ends of the straps' kbuckles aresecured, by which straps 4; and 5 can be connected'to each other.Bymeans of said straps the non-slip tached, or removed, in a fewmoments. Said non-slip device is therefore particularly adapted forshort escents, say, in training fields or for travelling on hillyground. Owe

ing to its small size, a pair of such non-slip dev1ces, after removal,may be tucked into a rucksack, or pocket of a-coat, or fastenedto thebelt, so as to bealways ready' for use. Said device doesnot injure aneventually present non-friction wax layer.

WVhat I claim is: i 1. A non-slipdevice for use with prising metal teethadapted to be fastened to the bottom of said skis, said teeth having atriangular cross section. V

2. A non-slip device strip of leather secured thereto and metal teethsecured to said strip of leather.

3. A non-slip device for use with skis comprising a support strip ofleather secured to said support, metal teeth secured to said strip ofleather and skis comfor use with skis com-- 1 prising a support ofwater-proof fabric, a an embodiment of the 111- of water-prooffabric,.a'

means attached to said support for securing said device to a ski.

4:. A non-slip device for use with skis comprising a'support ofwater-proof fabric, a strip of leather secured to said support, metalteeth secured to said strip'of leather and straps attached to saidsupport. M

5. A non-slip device for use with skis comprising a strip of leather,metal teeth secured to said strip of leather and the free ends of saidteeth being inclined with respect to the surface of said strip ofleather.

6. .A nen-slip device for use With skis comprising a support, a strip ofleather secured 1 to said support, metal teeth secured to said strip ofleather, straps attached to said sup port and buckles secured to saidstraps Whereby said straps may be connected to one another for securingsaid device to said skis.

In testimony whereof I have signed my name to this specification.
